Ragland met some members of the royal family in the days leading up to the nuptials, including Prince Charles, his wife Camilla, the Duchess of Cornwall, the Duke and Duchess of Cambridge and Queen Elizabeth. We asked body language experts to analyze Ragland's behavior, posture and interactions with the royal family on the wedding day.

The public got a first glimpse of the bride and her mother as they pulled up to the chapel together, a moment captured in the image below.

Meghan, now the Duchess of Sussex, arrives at St. George's Chapel with her mother, Doria Ragland.

Body language expert Traci Brown, author of Persuasion Point: Body Language and Speech for Influence, noted that Meghan and her mom have similar ― though not identical ― excited expressions on their faces. Meghan's smile appears more relaxed than her mother's, which makes sense because Ragland isn't as accustomed to being in the limelight.

"Her mom has her eyebrows raised and we can see more of the whites of her eyes. That says surprise," Brown said. "I bet she's just a tad overwhelmed with the crowds and attention. It's understandable that she's not going to be quite as used to the attention as her daughter, who's spent the last year or so getting used to it. But she's done a good job of practicing her beauty queen wave!"

Many royal wedding viewers also took note of Ragland's interactions with Charles, who appeared to be going out of his way to make sure she felt comfortable and included.

"There is a saying in the U.K.: to be 'treated like a Duchess,' which means to be treated like royalty and given great service, respect and honor," Bowden said. "Prince Charles shows Doria, the only family member present from the bride's side, exactly the same physical treatment as the duchess on his other arm."

"Though we could say this is just being polite, there is an etiquette in the royal circles which also bears huge weight and significance," he added.

Brown also noticed that Charles acted protective of Ragland, and that Ragland seemed to depend on him in return.

"We always see her standing close with a hand on him," Brown said. "I'm sure she's not used to the kind of hubbub they're all experiencing so we see her reach for the calming support."

Throughout the day, Charles seemed to make an effort to make Ragland feel welcome.

Charles frequently responded by resting a hand on Ragland and looking her in the eyes, as to give her his full attention.

"Even on Harry's way out of the church, we see the groom look back to check on the family, only to find that Charles is taking care of Meghan's mom," Brown said.

An unnamed royal staffer told Vogue last week that Ragland and the royal family "all got on extremely well" during their pre-wedding sit-downs ― a sentiment that Brown observed during the actual nuptials.

"They've really embraced her as part of the group, showing their full support and just how classy they are," she said.
